1) You and a friend should have the same game (the game must be Ad Hoc compatible, you can check whether it's Ad Hoc or not by looking at the back of the UMD box).
2) You must have a game that is Ifrastructure compatible.

The difference between the two of them is that Ad Hoc is just for a friend near you. Infrastructure is for playing against anyone in the whole world that has that game.

I've posted a thread about this but nobody has replied,so I just want to ask if Coded Arms is a popular game.I know it sounds like it's not relevant to this thread but when I go online nobody else is on the lists.I've tested my connection,went successful,i went on Google using my PSP,again,very successful.But when i go onto Coded Arms there is NOBODY on!I tried and tried but no success at all.I haven't tried using other games but I'm just so excited about this game because it is totally AWESOME!Plus I DLed it for 50mb LOL.

P.S. I'm using my PSP right now but it took like half an hour just to get half of the text up there.LOL anyways please help me thanks.
